SHOE-BEATING MACHINE.

Application filed September 15, 1919.

T 0 all whomit may concern.

Be it known that I, Crnns D. Fore, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Shoe-Beating Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes and particularly to that type of shoe shaping machine, known as a rotary beater, the general organization of which is shown in United States Patent No. 1,030,837, granted June 25, 1912, on an application of Orrell Ashton.

This type of machine comprises a rotary beater made up of a hub provided at its ends with a pair of flanges between which extend rods upon each of which is mounted a member or members, such as a series of rings or a stout helix, the interior diameter of which is substantially greater than the diameter of the rod. This arrangement provides that thesemembers shallstand out radially from the hub by centrifugal action while the heater is rotating and may yield inwardly when they strike the work and glide over the work in rubbing contact therewith. It has been found, however, during theextensive use into which this machine has gone, that the rotation of the rods with respect to the flanges, caused by the backward swing of the helixes or rings over the rods, coupled with the severe outward pull of the helixes or rings due to centrifugal force, wears the end portions of the rods to such an extent as sometimes to cause breakage, throwing the parts thus released violently from the machine to the imminent danger of the operative and all other persons in the vicinity.

It is the object of my invention, accordingly, to provide a simple and effective means to prevent the rotation of the rods in the flanges, and thus obviate their wear and overcome the possibility of such an accident as that described. In the preferred form of the invention illustrated, I accom plish this by extending each of the rods a short distance at one end beyond the supporting flange, and cutting away part of Specification of Letters Patent.

modifications might easily be made without I departing from the spirit thereof.

The several features of the invention, including certain details of construction and combinations of parts will be described in the following specification and particularly pointed, out in the claims.

In the drawings,

F 1g. 1 is a perspective view of so much of the machine as 1s necessary for an under-' standing of my invention;

Fig. 2 is a cross-sectional view, partly broken away, through the rotary beater ele ment; and i I rods.

In the exemplified embodiment of the invention, the frame of the machine suitably Fig. 3 is a perspective view of one of the I i supports a shaft 6 on which is mounted a hub 8 provided at itsends with a pair of' flanges 10. Each of these. flanges is pro-- vided with a circular series of holes supportlng the respective ends of a series of rods 12 each of which is provided. with. a

suitable beating element, such as a stout helix or a series of'rolls 14, having an opening of substantially larger diameter than that of the rods 12. 'To restrain the rods '12 from endwise movement there is provided a pair of flat rings 16 and-18 suitably attached to the remote surfaces of the flanges as, for instance, by screws 20. To prevent rotation of the rods 12in the flanges each of the rods is extended at one end beyond the flange, and has a portion of its material cut away, as shown in Fig. 3, leaving a substantially semi-circular segmental extension 22 the flat surface of which engages the periphery of the ring 18.

It will thus be seen that I have provided an exceedingly simple yet very effective means for preventing the rotation and conse uent wear of rods 22.

aving described my invention, what I rods, a pair of rotatable supports for the respective ends of the rods, each of said rods being formed at one end unsymmetrically with respect to its axis, and a ring engaging said unsymmetrical portions to prevent rotation of said rods.

3. In a'machine of the class described, a rotary beater comprising an annular series of'rods, a pair of rotatable supports for the respective ends-o1. the rods, each ogt said rods having a portion at one end formed unsymmetrically with respect to its axis, and a ring engaging said unsymmetrical portions to prevent rotation of said rods.

at. In a machine of the class described, a

rotary beater comprising a carrier having end flanges, a series of cylindrical rods having their ends supported in said flanges, separate beating elements rotatively supported by said rods between the flanges, each of the rods having a portion of its length formed unsymmetrically with respect to its axis, and means engaging said unsymmetrical portions to prevent rotation of the rods in said flanges.

5. In a machine of the class described, a rotary carrier having end flanges, an annular series of rods having their ends supported in said flanges, beating elements mounted on said rodsbetween the flanges, each of said rods having at one end a portion of its periphery flattened, and a ring engaging saidflat portions of the rods to restrain them against rotation in sald 6. In a machine of the classdescribed, a

ea ers rotary beater comprising a carrier havingend flanges, a series of rods having their ends supported in said flanges, beating elements mounted on said rods between the flanges, each of the rods having one. of its ends projecting through one of the flan es and formed as a segment of a circle, an a ring secured to said last mentionedflange and engaging the flat sides of said segments to restrain said rods from turning in said flanges.

7. In a machine of the class described, a rotary beater comprising a carrier having end flanges, a series of rods havingtheir ends supported in said flanges, beating elements mounted on said rods betwecn the flanges, each of said rods being atone end substantially semi-circular in crosssection, and a ring engaging the flat sides ofsaiid semi-circular portions to prevent rotation of said rods in said flanges.

8. In a machine of the class described, a rotary beater comprising a carrier having endflanges, a series of rods having their ends supported in said flanges, beating elements mounted on said rods between the flanges, a pair of rings attached to theremote surfaces of said flanges'and overlying the ends of said rods to restrain them from endwise movement, and a projection-at one end of each rod engaging one otthe rings and formed and arranged to restrain said rods against rotation in said flanges.

9. In a machine of the class described, a rotary beater comprising a carrier having end flanges, a series of rods havingtheir ends supported in said flanges, beating elements mounted on said rods between the flanges, a pair of rings attached to the remote surfaces of said flanges and overlying the ends of said rods to restrain them'from endwise movement, and a projection at one end of each rod engaging the periphery of one of the rings and formed and arranged to restrain said rodsjagainst rotation in said flanges.

In testimony whereof I havesigned my name to this specification.
